A bowl of Cajun Andouille potato soup with corn brings together smoky sausage, soft Yukon Gold potatoes, sweet kernels, and a gently creamy broth. Bell pepper, celery, onion, garlic, and Cajun seasoning build a familiar Louisiana-inspired base, while a little cream rounds out the spice. It is filling enough for supper and comes together in one pot in about 45 minutes.
This version keeps the potatoes chunky instead of blending the whole pot. Some pieces soften into the broth and give it body, while the rest stay tender and distinct. Browning the sausage first also leaves savory bits in the pot, giving the vegetables a head start on flavor before the stock goes in.
Why you'll love Cajun Andouille potato soup with corn
Every spoonful has a little contrast: smoky, savory sausage; mellow potato; and sweet corn to balance the Cajun spice. You can adjust the heat with the seasoning blend and hot sauce at the table, so the soup can be lively without overwhelming anyone.
It is practical for a chilly evening because everything cooks in one Dutch oven or soup pot. The potatoes do not need to be peeled if their skins are thin and clean, and frozen corn can go straight into the pot. Serve it with warm bread or a crisp salad, and dinner is ready without much fuss.
The recipe also makes generous leftovers. As it rests, the starch from the potatoes thickens the broth slightly. A splash of stock or milk loosens it when reheated, and the flavors are especially cozy the next day.
Ingredients for the soup
This recipe serves 6. Set out the ingredients before you start so the vegetables can go into the pot while the sausage is still warm.
- 12 ounces smoked Andouille sausage, sliced into 1/4-inch half-moons
- 1 tablespoon olive oil, if needed
- 2 tablespoons unsalted butter
- 1 medium yellow onion, diced (about 1 cup)
- 1 medium red or green bell pepper, diced
- 2 celery ribs, diced
- 3 garlic cloves, minced
- 1 tablespoon all-purpose flour
- 1 tablespoon Cajun seasoning, plus more to taste
- 1/2 teaspoon smoked paprika
- 1/4 teaspoon dried thyme
- 2 pounds Yukon Gold potatoes, cut into 3/4-inch cubes
- 4 cups low-sodium chicken broth
- 1 cup frozen or fresh corn kernels
- 1 cup heavy cream
- 1/2 cup whole milk, plus extra to thin if needed
- 1/4 teaspoon black pepper, plus more to taste
- Sliced green onions or chopped parsley, for serving
- Hot sauce and lemon wedges, optional
Andouille is smoked and seasoned, so salt levels vary by brand. Start with low-sodium broth and wait until the soup is finished before adding extra salt. If you cannot find Andouille, use another fully cooked smoked sausage and add a pinch of cayenne or extra Cajun seasoning for the missing heat. Yukon Golds hold their shape while lending a creamy texture; russet potatoes also work but break down more readily.
Step-by-step instructions
- Brown the sausage. Set a large Dutch oven over medium heat. Add the Andouille in a single layer and cook for 4 to 6 minutes, turning occasionally, until browned at the edges. Transfer it to a plate, leaving about a tablespoon of rendered fat in the pot. Add a little olive oil if the pot looks dry.
- Soften the vegetables. Add the butter, onion, bell pepper, and celery. Cook for 5 to 6 minutes, stirring now and then, until softened but not browned. Stir in the garlic, Cajun seasoning, smoked paprika, thyme, and black pepper; cook for 30 seconds so the spices smell fragrant.
- Make a light thickener. Sprinkle the flour over the vegetables and stir for about 1 minute. It should coat the vegetables without clumping. Pour in about 1/2 cup of broth while stirring to smooth out the flour, then gradually add the remaining broth.
- Simmer the potatoes. Add the potato cubes and bring the broth to a gentle boil. Lower the heat to maintain a steady simmer, partially cover the pot, and cook for 14 to 18 minutes. Stir once or twice. The potatoes are ready when a fork slides into the center of a cube with little resistance.
- Add the corn and dairy. Stir in the corn, cream, milk, and browned sausage. Simmer gently, uncovered, for 4 to 5 minutes, just until the corn is hot and the soup is steaming. Avoid a hard boil after adding the cream, which can make the texture less smooth.
- Adjust and serve. Taste the broth. Add more Cajun seasoning, black pepper, or salt as needed. For a thicker bowl, mash a few potato pieces against the side of the pot and stir them back in. Ladle into bowls and top with green onions or parsley. Offer hot sauce and lemon wedges at the table.
Tips and variations
Control the spice
Cajun blends differ: some are mostly paprika and herbs, while others bring substantial cayenne and salt. Begin with 1 tablespoon, taste after the potatoes are tender, and add more in small pinches. If your sausage is very spicy, keep the soup mild and let everyone add hot sauce individually. A squeeze of lemon can brighten the broth without adding more heat. To keep Cajun Andouille potato soup with corn balanced, season in stages and let the sweet kernels temper the spice.
Make it thicker or lighter
For a rustic, chunky bowl, leave the potatoes intact. For a thicker soup, use the back of a spoon to mash a few cubes, or blend one cup of broth and potatoes and stir it back in. An immersion blender can be used briefly, but avoid blending the sausage and corn if you want their texture to remain distinct. To make the soup a little lighter, replace half of the heavy cream with whole milk; the broth will be less rich but still creamy.
Easy swaps
- Use frozen corn when fresh corn is out of season. No thawing is needed.
- Stir in a handful of chopped kale or spinach during the last few minutes for a leafy finish.
- Use vegetable broth and a plant-based smoked sausage for a meat-free variation; check the seasoning because different sausage brands vary.
- If you like a little more sweetness, add 1/2 cup of diced carrots with the onion and celery.
For a bigger comfort-food spread, pair the soup with creamy corn casserole or a slice of Southern cornbread dressing. For another bowl with Cajun seasoning, try creamy Cajun white chicken chili. If smoky sausage and potatoes are your favorite combination, this one-pan smoked sausage and potato skillet is another hearty dinner idea.
Storage and reheating
Cool leftover soup promptly and refrigerate it in a shallow, covered container. FoodSafety.gov lists soups and stews for 3 to 4 days in the refrigerator and 2 to 3 months in the freezer; see its cold food storage chart. The potatoes soften a little after freezing, but the soup remains tasty.
Reheat a portion on the stovetop over medium-low heat, stirring often, until steaming. Add broth or milk a tablespoon at a time if it has thickened overnight. For a larger batch, warm it gently in the pot and avoid a vigorous boil once the cream is in. If frozen, thaw the container in the refrigerator overnight before reheating. Garnish with fresh green onion after warming to bring back a crisp, fresh note.
Frequently asked questions
Can I make Cajun Andouille potato soup with corn ahead?
Yes. Cook the soup, cool it promptly, and refrigerate it for up to 3 to 4 days. The broth thickens as the potatoes rest, so stir in a little milk or chicken broth while reheating. If you know you are making it ahead, you can hold back the cream and stir it in as you reheat.
What can I use instead of Andouille sausage?
Smoked kielbasa or another fully cooked smoked sausage makes a good substitute. Add a small pinch of cayenne if you want more heat, and taste before salting because both sausage and Cajun seasoning can be salty.
Do I have to peel the potatoes?
No. Thin-skinned Yukon Gold potatoes can be scrubbed and diced with the skins on. Peel them if you prefer a smoother, more classic chowder-like texture or if the potatoes have thick, rough skins.
Can this soup be frozen?
It can be frozen for up to about 2 to 3 months for best quality. Cream-based soups may separate slightly after thawing, so thaw overnight in the refrigerator and reheat gently while stirring. A splash of milk can help bring the broth back together.
How do I make it less spicy?
Choose a mild smoked sausage, start with 2 teaspoons of Cajun seasoning, and taste before adding more. Skip cayenne and hot sauce. The bell pepper, corn, and cream give the soup plenty of flavor even when the spice is restrained.
